Render to less than 1 fps

In Vegas there is a possibility to subsample when rendering by setting the frame rate directly.
However as far as I can see, it can not be set under 1 - as anything lower will be "rounded" up to 1.
For a test with a "cartoon look" I would like to create a video with 0.5 fps or lower.
Can this be done in Vegas or in a plugin??

It depends on exactly what you are trying to do.

Undersample still plays your video at the same speed, but "freezes" one frame for a period of time. In this situation, not all frames are displayed: frames are skipped.

Playback rate plays ALL the frames, but at a much slower rate. If you disable resample for the event, then no intermediate frames are created. Thus, each and every frame will be displayed for the amount of time required to achieve the desired slowdown.

Thus, if you want to display every frame, but at a slower rate, select the event, select "disable resample" and then click on OK. Then, insert right-click on the event and insert a velocity envelope. Right-click on the initial point and set the playback rate. You can select anything down to 1%.

If you want the same playback rate, but want to undersample that to achieve one frame every two seconds, I think you will have to do several renders (i.e., set the undersample to 0.1, render, bring that event onto the timeline, and do it again.

That won't quite do it, unless you set the frame rate of the output file lower too, and some formats are very uncooperative about that.

What you could do is set the undersample to 0.1 and the playback speed to 6x (combine playback rate and velocity envelope). Render this to a new file. Bring it back into Vegas and set the playback speed to 0.167 to return it back to normal speed. Of course, do all this with resampling disabled.

Edit, arggg ... brain not working right after a big lunch ...

I haven't tried what i outlined above, but i suspect that won't work either. So ... render a new version at 6X, then bring that new version in and undersample it to 0.1 and render to a new file. Then bring that second new file in and render again to 0.167x. I think it will take all three steps to achieve it.

Just tried some of the proposals - but one thing I had not thought of: I can not just lower the framerate - it looks strange - but I have to make the pics change to the music - have already made a few do so - and that seems to be the right thing.
Takes some time though - but thinking of the finished video that is no problem :-)
